Step-by-step explanation:
<span>Each smaller donation was for $20
The largest donation was $15 greater than the smaller donation.
First, determine the size of each donation. Since they are in a ratio of 4:4:7, it's easiest to add the ratios together (4+4+7) = 15. Then divide the total donation by that sum (75/15) = 5. Finally, multiply 5 by each of the ratios.
5 * 4 = 20, 5 * 4 = 20, and 5 * 7 = 35
So the 2 smaller donations were $20 each, and the largest donation was for $35.
The largest donation was $35 - $20 = $15 larger than one of the smaller donations.</span>
